CASH-REGISTERING DEVICE.

SPECIFICATION forming part of Letters Patent No. 399,080, dated LVi'arch5, 1889.

Application filed June 6, 1888. Serial No. 276,199. (No model.)

To aZZ whom it may concern:

Be it known that I, OTTO C. RETsLOFF, of IVinneba-go City, in the countyof Faribault and State of Minnesota, have invented certain new anduseful Improvements in Cash- Registering Devices; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in cash-registers.

The particular object of this invention is to provide a simple andreliable device which, when properly operated, will enable a merchant tokeep an accurate account mechanically of the aggregate amount of hissales for a definite period of time, and also with the same machineregister the net cost of articles cost of goods sold may be deductedfrom the gross receipts registered. at the same time, and thus afford anaccurate means for arriving'at the sum of profits arising from a dayssales.

Vith these objects in view my invention inafter described, and pointedout in the claims.

the upper projecting part, )3, of the case it will be suitably inclinedto furnish a surface for use as a desk on which to write, if desired, alock being provided to secure the door closed when the device is readyfor use as a register.

The shaft C is located horizontally within the case A, near the centerof the latter, and has its ends attached to the sides of the case. Thebody of the shaft preferably made square in cross-section and of such adiameter as to properly support other parts, which will now bedescribed.

On the shaft C a series of circular registering-disks, D, of equaldiameter, are placed, their peripheries beinglz'iterally flanged toprovide true circumferential faces D of proper breadth to be spaced intoequal divisions, that y are numbered to correspond with the differsoldsuccessively, so that the total amount of cut denominations of currencyin use, as will be more fully described farther on.

As I prefer to construct the register, there are eighteenregister-disks, D D, arranged in two series. These disks are providedwith a device to move them and expose their graduations and numberssuccessively at a proper consists in certain features of constructionand combinations of parts, which will be here- Referring to the drawingsmaking a part of this specification, Figure 1 is a front elevation inperspective of the cash register with the door closed. Fig. 2 is a frontelevation with the door lowered to expose the inof equal diameter andlength.

l l l point, and as these actuating devices are duplicates of each otherI will describe the actuator for one disk, which will answer for all.

On the shaft C eighteen hubs, E, are placed, 7 The disks are mounted onthese hubs and the latter intervene between the disks D.

The ratchet-wheels F are equal in number 1 to the disks D, and arepreferably of the same 3 diameter therewith. the device, taken Fig. 5 isa detached j the registering mechanism, the spring device which reversesthe wheels to return them to zero being also shown.

A represents the case of the machine,which is preferably made of wood.with a projecting front portion, A near the base below the registeringmechanism, which is adapted to receive a sliding drawer, B, in whichcash is contained.

The front lid or door, A, is made to hinge at its lower edge, and whenlowered to rest on It is rectangular horizontal bar, I, (see Figs. 2 Ecured.

These disks and wheels are paired, and each pair is held together spacedapart by a metal ring, G, belts or screws being inserted through thewheel F, ring G, and disk D.

Upon the hubs E the volute springs II are mounted, the inner ends ofsaid springs being attached to the hubs by pins c or other means, andthe outer ends to the pins (7, which project from the inner side of theratchetwheel F. Each ratchet-wheel has one hundred teeth, whichcorrespoi'id to the spaced numerical series on the faces of the disks.

IVithin the casing and across its front a and 4,) is se- This bar ispreferably in close proximity to the disks, and immediately over eachdisk it is provided witha sight-hole, g, through which the figures ontheir peripheries are exposed. Beneath each ratchet-wheel F a slidebar,J, is supported in boxes 0 0. Each slidebar is provided with anupwardly-projecting arm, 71, terminating in a pawl, 1', adapted toengage the teeth of its adjacent ratchet-wheel, the arm 7: being pivotedat a point, f, to the slide-bar J, so that it may have a limitedvibratory movement. The pawl i is of such a relative length that it mayengage the teeth of the ratchet-wheel F, it being pushed upward by aspring, 71 which seats between projecting studs m, that are aflixed tothe adjacent surfaces of the slide-bar J and the pivoted arm 71. The armI: is upwardly and outwardly projected from the pivotal point f, toaiiord a handle, 7L, by which to vibrate the arm and detach the pawlfrom the teeth of the wheel. By the employment of thisrearwardly-projeoting arm means are provided for the easy manipulationof the pawl h i when it is desired that the disk shall be allowed torotate back to zero-to the start-ingpointready for a new daystransactions.

The slide-bars J are each provided with collars 22, secured thereon atsuch proper points from the rear ends of the bars that the spiralsprings K, mounted on them and situated between the rear box, 0', andthe collarn, will by their expansive force normally hold the frontendsof the slide-bars projectedfoi f wardly until the collars p abutagainst-the inner faces of the front boxes, 0. Each slide bar has apush-button, r, formed on its front end, and it is evident that apressure i11- wardly of any button will actuate the wheel F and disk D,to which it is connected, every, reciprocal movement of the barrevolubly moving the adjacent wheel and disk one space to expose anumber at the sighthole in the bar I.

To insure a lock after each positive action of the wheels and disks eachratchet-wheel is engaged by a detent-pawl, s, all of these pawls beingpivoted on a supporting-shaft, M, which extends from one side of thecase A to the opposite side, with its ends secured thereto.

The levers S, upon which the pawls s are attached or made integralwith,'are extended forwardly to permit their free front ends to beoperated by hand and be raised simultane ously with the disengagement ofthe lower pawls, 5, so as to permit the wheels to be reversed and setback to zero by action of the springs H when said springs have beencoiled or partially coiled by the registration of a days sales.Projectinglaterally from each disk is a pin, 0, and projecting inwardlyfrom bar I'is a stop, 0'. The pin 0 is preferably set opposite thezero-point, and is designed to limit the reverse action of the disk andratchet-wheel when released by the disengagement therewith of the pawlss and i, and thus always stop the disk by its contact with the stop 0,so as to expose zero through the sight-hole.

As before stated, there are eighteen wheels and eighteen disks, eachregistering-disk and its actuating ratchet-wheel beingheld to movetogether. Nine of the disks constitute a series for registration of thecash sales or money received. These I preferablylocate in series on theshaft to the right of the inedian line. The other nine pairs ofconnected wheels and disks are designed to register the net cost ofgoods sold. At the same time the gross amount of receipts on each saleis put upon the right-hand side of the machine.

To afford a means for the proper registration of any amount within thecapacity of the machine, I employ the nine registers in each set. Thefirst disk to the right and the left of the center line in each seriesis numbered from 0 to 100, inclusive. The second disk is numbered inalternating order from 0 to 200 by twosas, for instance, 0, 2, 4, 6, 8,10, &c., ending with ($2.00. The third disk is numbered by fives, thus:0, 5, 10,15, 20, and so on up to the last sum on the face of thisdiskwheel, Which is $5.00. The fourth disk is numbered to representtenths of dollars marked on its face, thus: 0, 10, 20, 30, 40, 50,&c.,up to $10.00. The next disk in order represents fourths of dollars,thus: 0, 25, 50, 7 5, 100, &c., up to $25.00. The sixth disk isgraduated in sums of half-dollars, thus: 0, 50, 100,150, 200, die, up to$50.00. The seventh disk*i s divided to represent $100, from one dollarup, thus: 0,1,2, 3, &c. The eighth disk represents sums of which $5.00is the unit, thus: 0,5, 10, 15, &'c., to $500.00, and the last or ninthdisk is numbered from $10.00 to $1,000, inclusive. By this registrationof. cash receipts a clerk can rapidly register any sale from one cent tothousands of dollars by operating the proper slide-bars or the buttonsattached to their front free ends, it being understood that the seriesto the left of a center line is operated to put up the cost amount ofeach sale at the time the gross receipts for such a sale is registeredon the right side of the machine.

It is evident that if it is desired to prevent customers fromascertaining the cost of goods after purchase by closely noticing theopera.- tion of the register, this maybe done by using any arbitrarysymbol to represent a; 1111- merahor letters of the alphabet may be usedin lieu of figures, and thus concealthe cost of the article sold. V Inusing the device to register the gross rece'ipts of a days sales in astore or other place where articles of merchandise are sold, and whereit is desirable tokeep an exact account of the several sales throughouta day or other specified period of time, the several disks are allreturned to zero by the means already explained. They are then ready foruse and the case is closed and locked. Now, each sale is registered byputting the dollars and cents upon their respective disks to most IIOreadily give the aggregate amount, and at the same time the actual costof the goods or bill sold is registered on the other series ofregistering-disks.

At any time an inspection is to be made the gross amount of sales can beread and the cost of the goods ascertained, so that it is a simplematter to determine the actual profit of a days business.

Slight changes might be made in the details of construction of thisdevice without departure from the spirit or exceeding the scope of myinvention; hence I do not wish to restrict shown; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

nation, with the disk and ratchet-wheel, of a push-bar provided with aretraetile spring, a pawl pivoted to the push-bar and provided with arearwardly-projecting arm, and a spring, 7:, interposed between thepush-bar and pawl, substantially as set forth.

2. In a cash-register, the combination, with 1 suitable frame-work and ashaft journaled therein, of two distinct sets of disks mounted 1 on saidshaft, each disk being adapted to rol tate independently of the others,a ratchetwheel secured to each disk, a spring to rotate l l l l as setforth.

3. In a cash-registering device, the con1bii nation, with suitableframe-work and a shaft 1 jonrnaled therein, of two distinct sets ofdisks mounted on said shaft, each disk being adapted to rotateindependently of the others,

I figures or characters denoting dillferent dcits construction to theexact forms herein nominations of money on the disks, a bar in front; ofthe disks having sight-holes, pins on said bar to engage pins projectingfrom the disks, a ratchet-wheel on each disk, springs to i rotate thedisks in one direction, a push-bar 1. I11 a cash-registering device, thecombifor each disk having a retractile spring, spring-sustained pawlspivoted to said pushbars to rotate the disks positively, and dogs forlocking the disks against return movement, substantially as set forth.

In testimony whereof I have signed this specification in the u-escnce oftwo subscribing witnesses.
